What can I do with 40+ LM2111N IC's ? (Audio IF amp IC's)

[k7elp60]

Hello. I have over 40 LM2111N IC's. The closest thing I can find to the correct datasheet (NTE708, cross referenced) says they are IF amplifier IC's. So... what is interesting that I can do with these? How useful are they? How do I test that the cross reference is correct? Is anyone familiar with these parts at all?

Note: I would likely be willing to share or trade a bunch of these to whoever can give me a good reason to want to do that, and an address in the US.

Thanks for your time.

I would be willing to buy 3 or 4. I have a US address and could use some for a couple projects.
If interested please PM me

Hello.
This Circuit is used in King Aircraft DME. I have use for it and more than willing to buy 5-10 ea. Just give me a price. I am located in Norway but that should be no problem. Tell me price I send you the Money and you put it in an envelope and mail it

Oh hey. Sorry for the long delay, some serious stuff happened to me IRL somewhat recently. So I must admit I haven't had any time for the forums.

Anyway... these chips.
If either of you guys PM me an address, I would probably be willing to just give you some minus the cost of shipping/postage. (Provided I have the time of course.) Should be like 2~5$ USPS priority mail.

Sorry again for making you wait so long for a reply.
